    I left it for last the last bit of drilling for the transistor mounting

    I am using 2 M5 bolts the kerafol Keraterm 86/82 I am using is good for 60 Nm and has a thermal conductivity of 6.5 W/mK

    Same time ago I was looking for CVD Diamond and at the time it was not made for this application now is available under the trade name Diafilm TM220 whit a conductivity of 2200 W mK (is it real)

    Either I win the lottery or they decide that I had a good idea after all


    But any way compare a M5 bolt to the M3 screw and think about it

    That is where the thermistor go right against the squarish tab camming out of the moss fet body there will be same sort of heat shrink around both to maintain contact

    That is the hottest spot nearest to where all the switching happens


    I seen them all over the place from open air to near the penny washers normally used to fit the dudas

    I feel that I am letting you down
    Thing is I got a new toy today after waiting for over a month for it to be delivered

    I am Waiting for HiFI Dog to pop around and lend same moral support as I am so scared to mess it up when fitting it to the V
    Will let you know how it sounds later 1.1 mV output on the Paradise ???
    And if not the paradise will it overload the XP10?
    But then the F5 need same serious output to be driven DSCF2653.jpgDSCF2655.jpg

    Later
